我尝试将 pax-exam 插件与 testng 集成，最终得到以下错误。但是它与junit一起工作正常。

知道这里出了什么问题吗？

以下是我的示例测试代码。我认为这是我们可以编写的基本测试用例。

import org.ops4j.pax.exam.Configuration;
import org.ops4j.pax.exam.Option;
import org.ops4j.pax.exam.spi.reactors.ExamReactorStrategy;
import org.ops4j.pax.exam.spi.reactors.PerClass;
import org.ops4j.pax.exam.testng.listener.PaxExam;
import org.osgi.framework.BundleContext;
import org.testng.annotations.Listeners;
import org.testng.annotations.Test;

import javax.inject.Inject;

import static org.testng.Assert.assertNotNull;
import static org.ops4j.pax.exam.CoreOptions.*;


@Listeners(PaxExam.class)
@ExamReactorStrategy(PerClass.class)
public class SampleTest {

    @Inject
    BundleContext bundleContext;

    @Configuration
    public Option[] config() {

        return options(
                mavenBundle().artifactId("testng").groupId("org.testng").versionAsInProject()
        );
    }

    @Test
    public void testBundleContextStatus() {
        assertNotNull(bundleContext, "Bundle Context is null");
    }
}

这是我使用的依赖项。

将 testng 依赖版本更改为 6.3.1 后，它可以正常工作。但是对于最新发布的版本，即 6.9.6 问题是存在的。

对问题的最新编辑包含答案。Pax Exam 4.6.0 是使用 TestNG 6.8.17 编译的，显然 TestNG 6.9.x 中存在不兼容的 API 更改。

Pax Exam 直接使用 TestNG 的一些内部类，因为没有更好的替代方案。

一般来说，最好将 Pax Exam 与 JUnit 一起使用。JUnit 集成得更好，在 OPS4J 和其他下游项目中具有更多的测试覆盖率和使用率。
